Troubleshooting connection errors:
*Are you using the right WSDL? Regenerate a new one
* Make sure that you are not cacheing soap requests. (It’s in the readme)
* If you’re switching from sandbox to enterprise make sure that you switched accounts when generating the wsdl
* Can you connect to the sandbox?
* Are you logging everything?
* Have you checked watchdog?
* Re-enter the token, user name and pass
* Try another user
* In Salesforce: Regnerate the wsdl
* If you’re switching from sandbox to enterprise, make sure you're in the right account
* Check the credentials associated with the user
* Make sure the ip of server is not blocked
* Go to: setup > users. Check login attempts of the user you are trying to connect with
*
*
* In the Salesforce API module: Replace both wsdl files with the one you want to use
* In the file salesforce.class.inc:
Find the line$this->client->createConnection($wsdl);
Before that line putdpm($wsdl);
* Make sure that the wsdl has .xml extension at the end.
* If you have devel installed: excecute php:
$somevariable = salesforce_api_connect();
dpm($somevariable);
* PHPinfo():
Check that soap is running.
Check that soap is not being cached.
Check that ssl is a Registered Stream Socket Transports.
* If you have shell access: curl https://login.salesforce.com
check that you get stuff
